Thanks. Just to be sure, you mean Ctrl followed by a semicolon (;) right? 
Unfortunately didn't work. M-; did though, and that's good enough.

Good question. I looked at my .emacs file and I think C-c C-c comes from 
the dwim thing:

;; Nice trick for commenting/uncommenting regions, using dwim (do what I 
mean)
;;
;;
;; Otherwise, to uncomment use C-u C-c C-c (opposite of C-c C-c to 
comment out)
;; The C-u trick works with latex too. 
;; Highlight region, then M-x comment-region. 
;; To uncomment, highlight, then C-u M-x comment-region.

(if (fboundp 'comment-dwim)
  (add-hook (if (boundp 'c-mode-common-hook)
               'c-mode-common-hook
             'c-mode-hook)
            (lambda ()
              (define-key c-mode-map "\C-c\C-c" 'comment-dwim))))

and similarly for C++, latex and matlab.
